Hi everyone, I’m new to Stata (using version 15.1 on Windows 10) and regard my statistical knowledge as rather basic.
I investigate how firms can take advantage of their investors' assets.
My data is organized as an unbalanced panel with firm ID as panel variable and report period as time variable. There are 149 firms and 490 observations.

For my first and second hypotheses my dependent variable is a 0.5-paced score ranging from 0 to 10. My independent variable is a dummy.

H1:
Dependent variable: revenues, rev_rating; 0.5-paced score from 0-10
Independent variable: theoretical fit, theo_fit; dummy, 1 if there is a potential fit between two specific entities, 0 otherwise
Controls: batch (categorical, 7 options), age (number of months, 23-100), year (controlling for the year in which rating has been performed; categorical, 3 options), status (categorical, 4 options), no_head (size in number of employees, 0-1,100), office (categorical, 12 options)

H2:
Dependent variable: rev_rating; 0.5-paced score from 0-10
Independent variable: cur_fit; dummy; 1 if there is an actual fit between the startup and another entity, 0 otherwise

Note: theo_fit=1 (independent variable in H1 and upcoming H3) is a prerequisite for cur_fit=1., but not all theo_fit=1 also have cur_fit=1

I got recommended to run xtologit and compare it with xtoprobit. However, I’m not sure whether this is the right thing to do since my dependent variable is a score rather than a dummy. I cannot run any fixed effects regressions because my independent variable doesn’t change over time and gets omitted. Does someone have other recommendations?

Moreover, I fear that my third hypothesis cannot be tested by regression analysis. Here, both, my dependent (current fit) and my independent (theoretical fit) variables are dummies moderated by another dummy variable (information sharing). I made a contingency table to check the frequencies of every possible outcome. Is there another way to analyze it?

H3:
Dependent variable: cur_fit
Independent variable: theo_fit
Moderating variable: information sharing, share_info

I ran

Code:
xtlogit cur_fit i.theo_fit##i.share_info


Code:

      0.theo_fit dropped and 302 obs not used

Hope this is enough information. If you lack anything let me know.

Thank you very, very much in advance!
